Performance that
drives rankings
Under 1 second loading time. PageSpeed score near 100. Core Web Vitals in the green. That's Astro – no tricks, no plugins.
Request performance checkWhy website performance determines your ranking
Google has made it clear: speed is a ranking factor. Since the introduction of Core Web Vitals, Google evaluates not just your website's content, but also how quickly and stably it reaches the user. Slow pages lose visitors and rankings – fast pages win both.
Astro websites are built for performance from the ground up. No JavaScript framework blocking the browser, no server working on every request, no database delaying response times. The result is loading times under one second – measurable, not perceived.
Core Web Vitals: Astro vs. WordPress_
Largest Contentful Paint
How quickly the main content becomes visible.
Interaction to Next Paint
How quickly the page responds to clicks.
Cumulative Layout Shift
How stable the layout remains during loading.
Why Astro is technically faster_
Zero JavaScript by default
Astro ships no JavaScript to the browser by default. Interactivity is only loaded where it's truly needed. This eliminates the biggest performance killer on modern websites.
No server rendering
WordPress rebuilds every page on every request: execute PHP, query the database, generate HTML. Astro pages are already built – the server just delivers static files.
Automatic image optimisation
Astro optimises images at build time: automatic WebP conversion, responsive sizes and lazy loading. WordPress needs an extra plugin for this – and even then, results are rarely optimal.
Minimal code footprint
No jQuery, no Bootstrap, no page builder library. Astro delivers exactly the code the page needs – nothing more. That means fewer downloads, faster parsing and faster rendering.
CDN-optimised
Static files can be perfectly distributed via CDNs (Content Delivery Networks) worldwide. Your website is served from the nearest server – no matter where your visitor is located.
No TTFB problem
Time to First Byte: with WordPress, the browser waits for PHP and the database. With Astro, it immediately receives a finished HTML file – TTFB under 100ms is standard, not the exception.
What performance means for your business_
Better Google ranking
Core Web Vitals are a direct ranking factor. Websites with green scores are preferred when relevance is equal – especially on mobile, where most searches happen.
Lower bounce rate
53% of mobile users leave a page if it takes longer than 3 seconds to load. Under 1 second loading time keeps visitors on the page – and increases conversion chances.
Higher conversion rate
Every second less loading time increases conversion by up to 7%. A fast website isn't a nice-to-have – it directly impacts revenue.
Better user experience
Fast, stable pages feel professional. No flickering, no jumping, no waiting. First impressions matter – and the first impression is loading time.
Frequently asked questions about website performance_
Why are Astro websites so fast?
Astro delivers pure, static HTML without JavaScript by default. There's no server assembling HTML on every request, no database being queried, no framework initialising in the browser.
What are Core Web Vitals and why do they matter?
Core Web Vitals are Google's metrics for user experience: LCP measures main content loading time, INP measures responsiveness, and CLS measures visual stability. Google uses these as a ranking factor.
How does Astro score on Google PageSpeed?
Astro websites typically achieve PageSpeed scores of 95–100 on desktop and 90–100 on mobile – without additional optimisation. WordPress sites often land at 60–85 even with caching plugins.
Does website speed affect Google rankings?
Yes, directly. Google has confirmed Page Experience as a ranking signal. Faster websites with good Core Web Vitals are preferred – especially on mobile.
Can WordPress be as fast as Astro?
Theoretically yes – with extensive optimisation. In practice, WordPress sites rarely match Astro because the server overhead (PHP, database) can never be fully eliminated.
